Scheduling workload synchronization based on real-time latency measurements

Abstract

A device includes a transceiver coupled to a processing device. The processing device is to determine a first time for executing an operation associated with a work execution agent of a plurality of work execution agent. The processing device is further to receive a latency measurement associated with the work execution agent responsive to transmitting the request.
